Abstract

A method for the conversion of mercaptoalkanols to dithiodiglycols having good color properties and low residual odor is provided. Mercaptalkanols are reacted in the presence of small amounts of anhydrous ammonia and an oxygen-containing gas in the absence of any metal-containing catalysts to produce the desired dithiodiglycol products.
